Abstract: A method for resizing write cache in a storage system is disclosed. In one embodiment, such a method includes maintaining, in a write cache, write data to be destaged to RAID arrays implemented on persistent storage drives. The method dynamically resizes the write cache in a way that takes into account the following: (1) an amount of battery power available to destage the write data to the persistent storage drives in the event of an emergency; and (2) underlying characteristics of the RAID arrays to which the write data is to be destaged. A corresponding system and computer program product are also disclosed.

Abstract: A method for destaging data from cache is disclosed. In one embodiment, such a method includes maintaining, in cache, modified data to be destaged to persistent storage drives. The method further detects an emergency situation wherein the modified data needs to be promptly destaged to the persistent storage drives. In response to the emergency situation, the method automatically disables artificially-imposed throughput limits associated with the persistent storage drives. The method then destages the modified data to the persistent storage drives without restriction from the artificially-imposed throughput limits. A corresponding system and computer program product are also disclosed.

Abstract: A data storage system includes multiple tiers of data storage accessible by multiple hosts. The multiple tiers include an upper tier having a lower access latency and a lower tier having a higher access latency. For each extent among a plurality of extents of file system objects in the data storage, the storage controller separately tracks, for each of one or more hosts that access the extent, a respective heat indicative of a frequency of access by that host. In response to an event disassociating a first host among the multiple hosts from a particular extent among the plurality of extents, the storage controller recalculates an overall heat of the particular extent while excluding a first heat of the first host for the particular extent. The storage controller migrates extents among the multiple tiers based on overall heats of the plurality of extents.
